iommu: set group default domain before creating direct mappings
iommu_group_create_direct_mappings uses group->default_domain, but
right after it is called, request_default_domain_for_dev calls
iommu_domain_free for the default domain, and sets the group default
domain to a different domain. Move the
iommu_group_create_direct_mappings call to after the group default
domain is set, so the direct mappings get associated with that domain.
